BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to the package field, especially to a package bag.

2. Description of Related Art

In the panel industry nowadays, liquid crystal glasses are usuallyapplying horizontal stacking method to dispose in the package case, andsimultaneously a pad layer is used to separate two glass panels next toeach other for buffer function and prevent liquid crystal panel adheringtogether when taking out a liquid crystal panel.

Liquid crystal glasses have higher criteria in package materials thatpads in use is free from dust, pollution or water-stains to preventpolluting or etching peripheral terminals or elements around liquidcrystal glasses, so present pads are packed by applying plasticspackages and then sealed by applying taps or thermo-pressing methods.However, plastics packages usually are polyethylene bags that preventingentering from dust or water stain entering from the air after sealing,but air inside and outside the bags cannot be able to ventilate toadjust the temperature and moisture inside the bags in time. After padsis packed well, surfaces of the pads inside the bags are usually havingwater stains to polluting or etching peripheral terminals or elementsaround the liquid crystal glasses due to higher temperature insidecompartments after long-distance transportation.

Or, the film includes a first film layer, and the first film layer ismade of Polytetrafluoroethene (PTFE) material.

Wherein, the film includes more than one mentioned first film layers anda dry layer disposed between two layers of the first film layers.

Wherein, the dry layer is a moisture-proof sheet.

Or, the dry layer is active carbon.

Wherein, the film is attached on one inside surface of the package bagbody.

Wherein, the film is attached on a side of the package bag body, and thearea of the side is smaller than those of other sides.

The package bag of the invention has good waterproof performance and airpermeability performance to keep clean and dry inside the package bageven at high temperature environment and effectively protects productsinside the package bag.

FIG. 2 is the local structure of schematic view of embodiment 1 of theinvention.

FIG. 3 is the local structure of schematic view of embodiment 2 of theinvention.

DETAILED DESCRIPTION OF THE EMBODIMENTS

To make the objects, technical solutions and advantages of the presentinvention will be more clearly understood, the accompanying drawings andthe following embodiments of the present invention will be described infurther detail. It should be understood that the specific embodimentsdescribed herein are merely for explaining the present invention and arenot intended to limit the present invention.

Embodiment 1

Refer to FIG. 1, the invention provides a package bag, comprising apackage bag body 10 and at least a film 20, at least a through hole 100is disposed on the top of the package bag body, and the film 20 withwaterproof air permeability is attached on a surface of the through hole100.

In this embodiment, the package bag body 10 is manufactured withpolyethylene material, and sealed by a tap.

As shown in FIG. 2, a package bag body is used for stacking a pluralityof pads 200 to achieve waterproof air permeability of film 20, and afilm 20 in this embodiment is a layer of a first film layer 21 which canbe made of foaming polyurethane material or Polytetrafluoroethene (PTFE)material here and both materials are with good heat insulation and airpermeability; in particular, when the first film layer 21 is made offoaming polyurethane material, which has several micro holes to achieveventilation inside and outside the package bag, and simultaneouslyprevent steam and dust from entering.

The film is attached on an inner surface of the package bag body 10 toprevent steam entering the package bag when being tore open by someunusual force.

It is understandable that the amount of through hole 100 can be disposeda lot, and correspondingly the film 20 adhere to an inner surface of acorresponding through hole 100. At least a film 20 is attached on a sideof the package bag body 10 at the same time, and the area of the side issmaller than those of other sides. The side is not covered when stackingmultiple package bags 10 with pads 200 on the larger area, and is ableto ventilate with air outside.

Embodiment 2

As FIG. 3 shows, this is the local structure of schematic view of theembodiment of the invention, and what differences from the embodiment 1is that the film 20 includes multiple first film layers 21 and a drylayer 23 disposed between two layers of the first film layers 21 in thisembodiment. Due to increasing the dry layer 23, an opening of the firstfilm layer 21 in this embodiment is larger a little than that in theembodiment 1 to ensure air inside and outside the package bag canexchange normally. Wherein, the dry layer 23 is a moisture-proof sheetor active carbon. The dry layer 23 can also act absorbing even whenlittle outside steam entering the film 20 by this kind of arrangementand preventing continuing entering inside of the package bag, which iswith well air permeability and simultaneously preventing water stainoccurrence happened inside the package bag more efficiently.

The package bag provided by the embodiment of the invention disposes athrough hole 100 on a surface of the package bag body 10, a film 20 withwaterproof air permeability is disposed correspondingly on the throughhole 100 to prevent dust and steam outside entering to the bag, and dueto the well air permeability performance of the film 20, the air insideand outside of the package bag can be exchange normally to prevent pads200 get wet from forming vapor due to different temperatures inside andoutside the package bags.

The above-described specific embodiment is only of the presentinvention, and it should be noted that those of ordinary skill in theart, in the present invention without departing from the principles ofthe premise, but also several improvements and modifications can bemade, these improvements and retouching also be considered the scope ofthe present invention.
